Windows Live Mail and OE6 have wrong day and time on emails

I have an issue with WLM and the emails it imported from OE6. I have an employee that said her emails were showing the wrong date, it was showing the current date not the actual day she had received it using OE6. I get her another computer to swap with and I moved the whole identities folder so she would have all her old emails on the new machine, a couple of days later she comes telling me its doing it again and also from the day I made the computer swap some emails are missing. I have checked the time zone settings those are correct, I have checked the webmail settings (we use rackspace) the settings are correct there also. I am just at a loss for what is going on and how to fix it. Any help would be greatly appreciated
